Slewing ring bearing (turntable bearing), is a bearing that able to bear a large axial load, radial load and overturning torque. Slewing bearings are generally accompanied with installing holes, inner gear, outside gear, lubricating hole and sealing devices, which enable mainframe structural compact in design, guide reliable, and easy to maintain.
Slewing bearings widely used in wind power generator, metallurgical equipment, lifting machinery, excavate machinery, construction machinery, port machinery, ships machinery, as well as precision radar missile launchers and large rotary device such as missile launcher.
